The Jenolan Caves (Tharawal: Binoomea, Bindo, Binda) are limestone caves located within the Jenolan Karst Conservation Reserve in the Central Tablelands region, west of the Blue Mountains, in Jenolan, Oberon Council, New South Wales, in eastern Australia. The caves and reserve are situated approximately west of Sydney, east of and west of Katoomba ( by road). Dating back to 340 million years ago, it is the oldest known and dated open cave system in the world.
The caves are the most visited of several similar groups in the limestone caves of the country, and the most ancient discovered open caves in the world. They include numerous Silurian marine fossils and the calcite formations, sometimes pure white, are noted for their beauty. The cave network follows the course of a subterranean section of the Jenolan River. It has more than of multi-level passages and over 300 entrances. The complex is still being explored. The caves are a tourist destination, with eleven illuminated show caves open to paying visitors.
The caves and conservation reserve are one of the eight protected areas that was inscribed in 2000 to form part of the UNESCO World Heritage-listed Greater Blue Mountains Area. The Jenolan Karst Conservation Reserve is the most westerly of the eight protected areas within the World Heritage Site. The reserve forms part of the Great Dividing Range and was listed on the (now defunct) Register of the National Estate in 1978. The Jenolan Caves are listed on the Australian National Heritage List.
Etymology The word Jenolan is believed to be an indigenous word for "high place"; derived from the Tharawal word, Genowlan, for a "high place shaped like a foot". An alternative (although highly unlikely) meaning comes from the name "J E Nolan" that was found smoked by a candle on the roof of a cave.
History
Geology By measuring the ratio of radioactive potassium and trapped argon gas, which was produced when the potassium decayed, scientists determined the age of the clay in the caves to be approximately 340 million years old, thereby making the cave complex the world's oldest known and dated open cave system. The Commonwealth Scientific and Industrial Research Organisation (CSIRO) in association with the University of Sydney and the Australian Museum lead the efforts in scientific research into the caves.
Indigenous culture For thousands of years, the Jenolan area has been part of the culture of local indigenous peoples. The area holds significance to the Gundungurra and Wiradjuri peoples, who knew it as Binomil or Bin-oo-mur, and a variety of similar names. A Dreamtime creation story of the Gundungurra people describes how the countryside came into being, and involves a struggle between two ancestral creator spirits – one a giant eel-like creature, Gurangatch, and the other, Mirrigan, a large native cat or quoll. The Gundungurra people penetrated the caves as far as the subterranean water, carrying sick people to be bathed in this water, which they believed to have curative powers.
European discovery There are no known contemporaneous accounts of the discovery of the caves by Europeans – though Charles Whalan is attributed as the first to conduct visitors to the caves in the 1840s. However, in Charles Whalan's obituary and other sources, credit for the caves' discovery is given to his brother, James Whalan. Though most accounts were written some decades after the initial discovery, and differ somewhat in the details, it is generally accepted that in 1838 (or possibly 1841), James Whalan was in pursuit of an ex-convict and active local thief named McKeown, who had stolen livestock, tools, clothing and a flour grinder, was tracked to the area. In this pursuit, James Whalan discovered the cave system and reported its existence to his brother Charles – who further explored the caves.
The caves, originally known as the Fish River Caves, came under the control of the NSW Government in 1866—becoming only the second area in the world reserved for the purpose of conservation. The following year, Jeremiah Wilson was appointed as the first "Keeper of the Caves". Wilson not only explored the already known Elder and Lucas Caves but later discovered the Imperial, Left Imperial (now known as Chifley), Jersey and Jubilee Caves.
The caves were open to tourism early, but there was little protection from visitors damaging formations until the collection of souvenirs and the writing of graffiti was banned in 1872. In 1884 the name Jenolan Caves was adopted.
The road to the caves originally went via , which meant that travellers from the south had to take a long, roundabout route of about 140km (90 mi) from Katoomba to Tarana, and, from there, to Oberon, New South Wales. In the mid-1880s, hotel keepers in Katoomba wanted to improve business by constructing a road to the Caves from their town, but the steep, rough ground between the caves and town was a major obstacle, and several attempts failed. However, representations were made to the Premier by Peter Fitzpatrick of Burragorang, who was connected to some mining operations near Katoomba. In April 1884, William Marshall Cooper, Surveyor of Public Parks for the State Government, was assigned the job, and worked out a horse-and-carriage track in a 10-day trek from Katoomba to the Caves. The route was, he remarked, 42km (26 mi) from the Western Hotel in Katoomba. "... Anyone accustomed to walking can do it comfortably in 12 hours ... when the proposed horse track is completed, it will be a very enjoyable ride of five hours." It became known as the Six Foot Track.
By 1885, Parliament had approved A£2,500 for the construction of Cooper's bridle track, with the work starting at the most difficult area, the Megalong Cleft, where a zig-zag had to be cut, partly in solid rock, to reduce the grade to 1:5.5."Track from Katoomba to Jenolan Caves" by W. M. Cooper, Surveyor of Public Parks, published in Sydney, Australia, 1885, copy at National Library of Australia (nla.map-rm1826-s2-e) The first recorded passage of the completed bridle track from Katoomba to Jenolan was by the Governor, Lord Carrington, in September 1887. Lord Carrington also made the first official visit to the caves at the completion of his journey, accompanied by Wilson.
In 1898 the current Jenolan Caves House was built, replacing the earlier wooden accommodation house built by Jeremiah Wilson, which had been partially destroyed in 1895 by fire.
J. C. (Voss) Wiburd became "Keeper of the Caves" in 1903 and discovered (with fellow guide and friend Jack Edwards) five more caves within eighteen months: the River, Pool of Cerberus, Temple of Baal, Orient and Ribbon Caves. He remained Keeper until 1932, when he left due to the Government's policy at the time of compulsory retirement at the age of 65.
The Chifley Cave, originally known as the Left Imperial Cave, was renamed in 1952 in honour of Ben Chifley, the Federal local member of parliament and former Prime Minister, who had died the previous year. In 1968, the Orient Cave became the first in the world to be cleaned, due to contamination by mud from the previous access route and a nearby coal boiler. The soot from the boiler was entering the cave via a new tunnel blasted 400 feet through to the Orient cave in 1954 to allow easier access (entering at Bat End). Steam cleaning was found to be damaging to the crystal formations, due to the rapid expansion and contraction caused by the heat from the steam, and these days water from the caves' own underground rivers is used if cave cleaning becomes necessary.
Since 2011, the CSIRO in association with the Australian Nuclear Science and Technology Organisation began using a new hand-held mapping system to map some of the caves in three-dimensional detail.
Caves Large portions of this extensive cave system are accessible only to experienced cavers, especially those areas along the underground river system.
Eleven show caves have been developed for regular tourism and are open to the public.
